TAMPA — Before Adam Warren was traded to the Cubs before the 2016 season, the right-hander was the Yankees’ player representative for the players’ union, so he understands the business side of the sport more than most.

Warren called the current state of affairs “concerning,” as dozens of free agents remain unsigned less than a week before pitchers and catchers are due to report to spring training and the MLBPA and the commissioner’s office lob public statements accusing the other side of wrongdoing.

“I think it’s a concern,’’ Warren said after working out at the minor- league facility on Friday. “You feel like baseball is in a great place right now. … The last couple of World Series have been great and you feel like baseball is at an all-time high in terms of interest, so you hate to see these kinds of things.”

A handful of teams — including the Yankees — have declared publicly they intend to stay under the luxury tax threshold of $197 million this season, while others have all but thrown in the towel on the season, which has caused the union and a few player agents to call out those not spending this offseason.

The unprecedented combination has left a wide spectrum of players searching for deals months after the hot stove season typically has closed.

There’s still time for free agents to find homes, but high-profile stars such as Yu Darvish, Jake Arrieta, Eric Hosmer and J.D. Martinez are out there, as are less expensive targets, such as Jon Jay, Melky Cabrera and Andrew Cashner.

The union, according to sources, intends to hold a camp at IMG Academy in Bradenton, Fla., beginning next week for those who haven’t signed.

“Hopefully we can get it worked out,’’ said Warren, whose player rep duties were handed off to Chasen Shreve. “It’s hard to say what exactly is going on … [but] all we want to do, is just play. Hopefully this won’t be going on too much longer.”
